Worlds Smallest Vertebrate

In this Aug. 2009 photo released by Louisiana State University, a frog sits on a U.S. dime in this photo taken by Louisiana State University herpetologist Christopher Austin near the Amau River in Papua, New Guinea. The species was claimed as the world’s smallest vertebrate on Wednesday, Jan. 11, 2012. Austin was studying the area’s rich biodiversity when he and graduate student Eric Rittmeyer found the frog, which they named Paedophyryne amauensis for the village of Amau. The frog out-tinied a Sumatran carp identified in 2006. Its discovery was reported Wednesday in the journal PLoS ONE. (AP Photo/Louisiana State University, Christopher Austin)
